any onwf e-.Sries'efpellets 42,.:hzwing' a central perforation ofappropriate size to co-operate with the desired core 41, may besupported in the desired vertical position by means of supporting lugs48 on frame l0, each pallet being preferably provided in its uppersurface with an annular seat 49 into which the lower end of thesectional mold 50 is seated,

For the purpose of holding the upper ends of the iii-olds or 50 inproperly centralized position, I provide pairs of plates 51, 51`

, a diameter slightly in excess of the diameter of the largest moldvwhich is to be used and, vin order that this perforation may becentralized with relation to the axis of any particular core which is tobe used, 'I provide the section 55 -withfslots 57 through which theretaining bolts 58 pass intol the main frame 10. YThe section 55 isprovided with 'a' chain 60 which may be utilized to support the segments12 in the position shown in Fig.

. 2 when-said segments are thrown back out of the way of `that portionlof the apparatus l which is utiliZed'in the formation of straight pipesections. v

In order to produce Ys, I provide a fitting or insert 71 (Fig. 7) 'whichmay be set in the lower end of a straight pipe mold 50,

vsaid insert being suitably' perforated in order to slip over a core 41.The upper face'72 of the insert 71 is appropriately formed,

as indicated in Fig. 7. to produce a beveled end of the pipe 'casting 73of such form that said casting may be cemented upon the side of astraight pipe which has been suitably cut away to lreceive it, so as toform :l` Y. v

Similarly, as shown in Fig` 8, I provide an insert 76 having acrotch-like upper end 77 forl use vin forming the stem of a T or rightangled Y. i i

I claim as my invention:

vl. A pipe vmolding machine comprising a main fra-me, a core carrierpivotally supported in said main frame, means lfor swinging said corecarrier inthe frame,-compris c ing a segmental gear on 'the carrier anda pinionmeshing with said gear, a curved i core.-means'for detachablyconnecting said curved core` to the carrier concentric with ythe'axis ofthecarri'er, a swinging mold support co-axial-with the core carrier andmeans for holding said mold'support in different positions ofv angularadjustment. Y

support co-axial with thecore carrier and v means for holding said moldlsupport in dif ferent positions of angular adjustment.

3. A pipe molding machine comprising a main frame, a core carrierpivotally supported in said main frame', a curved core, means for.detachably connecting said curved core to the carrier concentric withthe axis of the -'carrier, aswinging mold support co-axial with the corecarrier and means for holding said mold support in dii'erentpositions ofangular adjustment. l

4. A pipe forming machine comprising -a main body, a-curved core, meansfor supporting said curved core, a pivoted mold sup-- port having itsaxis concentric with the core, and means for holding said mold supportin different positions ofangular adjustment.

5. Pipe forming machine comprising a main framefa curved core carried bysaidI main frame, a mold support swinging about the axis of thecurvedcore, a cup-like. mold carrier carried by said mold support yandhaving Y a perforation through which the core is projected and means forholding the` mold support in different lar adjustment.

6. A pipe forming machine comprising a 'positions ofangumain frame, avsegmental 'core carrier journaled on the mainframe, a segmental= corecarried'by said carrier, a mold carrier swinging about the axis of thecore carrier, a cup-like mold receiver carried bythe mold carrier yandprovidedk withl a perforation through which the core is projected, andmeans for holding the ycore carrier in different positions of angularadjustment, and means for holding the mold carrier in differentpositions of angular adjustment.

7. A pipe forming machine comprising a:

main frame, VVa segmental' core carrier journaled on the main frame, asegmental core carried by said carrier, a mold carrier swinging aboutthe axis of the corecarrier,

and means for holding the core carrierinN different positions of angularadjustment,

and means for holdingy the mold` carrier in different positions ofangular adjustment.

8. In a pipe forming machine the combination with a core, of a tubularmold, means for holding said mold inl co-active relationship with thecoreyand aperforated insert sleeved into the mold'and over the core andprovided with an inclined upper face.v

9; In a pipe forming machine the combi- 1 nation of a core carrier, awork table hav- :ing a mold receiving perforation, means for holdingsaid table in various positions of` for holdingdsaid table in variouspositionsV of lateral adjustment upon the main frame.
